Alpine climbing is cold, and cold can drain your will and suck your soul. And that is why we made the DAS Pants: For summit pushes, extended cold-weather belay sessions and shiver bivies, these insulated pants boost morale with warm-when-wet 100-g PrimaLoft® Gold Insulation wrapped in a lightweight, PU-coated nylon ripstop shell (with DWR finish) that is durable, highly water-resistant and windproof. The sculpted fit maximizes warmth (though still sized as an over-pant), fully separating two-way side zips with insulated wind flaps allow easy on/off while wearing crampons and a harness, and the elasticized waist has hook-and-loop tab adjustments atop the side zips. The 2-way zippered fly has a snap closure, and the gripper-elastic cuffs accommodate an alpine boot and have snap-tabs to seal in heat. Stuffsack included.

Insulation

We use PrimaLoft® insulation inside insulated garments for its warmth, compressibility, and soft comfort. While the human body uses energy to stay warm, PrimaLoft insulation uses a patented microfiber structure to help the body retain warmth and conserve energy.

The proprietary ultra-fine fibers of PrimaLoft insulation form a tight collection of air pockets that trap heat from your body and keep the cold out, providing an excellent warmth-to-weight ratio. When insulation gets wet, it loses these air pockets and consequently, its insulating properties. PrimaLoft ultra-fine fibers were developed to be water resistant so your insulation stays drier and maintains its insulating properties even when wet.
